The focus was mainly on privacy, and the history of /e/ is well explained. Other projects also got some spotlight: Volla, Ubuntu Touch, Mudita Pure
Edit: the article is paywalled, sorry for getting your hopes up. I see it as a signal for mainstream appeal of /e/. The content of the article is well known for anybody in this forum. It’s giving an overview of parties involved and no indepth review of /e/ or the other alternatives itself.
